Abstract (en)
A method can stably produce a high-quality glass-particle-deposited body by depositing glass particles in an intended state, and a burner synthesizes glass particles. The method uses a burner comprising a material-gas-feeding pipe at its center. In one aspect of the method, while glass particles are synthesized with the burner to be deposited, the magnitude of bending at the tip of the material-gas-feeding pipe is maintained at a value of at most 1.2 mm. In another aspect, while glass particles are synthesized with the burner to be deposited, the magnitude of bending at the bottom end of the material-gas-feeding pipe is maintained at a value of at most 0.3 mm. Another burner for synthesizing glass particles comprises a material-gas-feeding pipe and a plurality of gas-feeding pipes for feeding gases needed to form a flame. In this burner, in at least one combination of neighboring two pipes among these pipes, the two pipes are mutually linked at a plurality of longitudinal locations. In this case, the at least one combination is or includes the combination of the material-gas-feeding pipe and the neighboring pipe. <IMAGE>
